There's a fine line between fishing and just standing on the shore like an idiot.

Facebook has recently rolled out it’s latest batch of updates, which of course means new optimized image sizes for your feed items.

So today I’ll be sharing with you the unofficial Guide to Facebook’s news feed image sizes, released by Gain, which you can view here.

Photo Posts
Facebook no longer crops photos, instead it resizes them. The maximum photo height is 394px and with of 470px. Facebook will resize a photo until the largest dimension fits the maximum space – filling the rest with white space.

Profile Images

Page profile pictures are square and display at 160×160 pixels on your Page. The photo you upload must be at least 180×180 pixels. We recommend uploading a square image. Rectangular images will be cropped to fit a square. Your Page’s profile picture will also display next to your Page’s name around Facebook to represent your Page.

You can be creative with how your Page’s profile picture and cover photo go together. On your Page, the profile picture is located 23 pixels from the left side of your cover photo and 210 pixels from the top of your cover photo.

Cover photos are 851 pixels wide and 315 pixels tall. If you upload an image that’s smaller than these dimensions, it will be stretched to this larger size. The image you upload must be at least 399 pixels wide and 150 pixels tall.

To get the fastest load times for your Page, upload an sRGB JPG file that’s 851 pixels wide, 315 pixels tall and less than 100 kilobytes. For images with your logo or text, you may get a higher quality result by using a PNG file.Cover Photo – 851×315 Profile Photo – 168×168

There is an old story about Abraham Lincoln spending vast amounts of time in the telegraph room of the War Department waiting for dispatches from his commanders in the field. One day, according to Lincoln biographer John C. Waugh, after a particularly long night, the president turned to the telegraph operators and said, “Well, boys, I am down to raisins.”

When asked to explain the phrase, Lincoln told the story of the little girl who celebrated her birthday by feasting on sweets, followed by raisins for dessert. Soon, she became violently sick and started throwing up everything she had eaten. Her concerned parents summoned a doctor, who upon investigating her issue, told the parents the danger was past and that she was “down to raisins.”

That’s us; that’s you and me, and certainly that’s the people in the Gulf region. We have all become so sickened by the events surrounding the collapse of the Deepwater Horizon and the broad-spectrum, oil-soaked destruction, which has not even begun to sink its teeth in, that we are all down to raisins.
